My invention relates to improvements in closure members or caps adaptedto eiiectively close and seal the mouths or openings of bottles.

jars, metal cans or other containers.

My invention relates more speciilcally to a device of the characterdescribed particularly adapted for use with bottles, Jars or metalcontainers that have a comparatively large neck or mouth.

While-the general construction of my improved closure-may be of thesnap-on type, generally similar to that shown and described in'U. S.Patent 2,339,343 issued January 18, 1944 to me, my present invention isdirected to a cap or closure of this type which is so constructed that atamper proof seal may be placed on the cover orclosure after the samehas been placed over the mouth of the receptacle and thecover or closurecannot be removedwithout breaking the seal.

The principal object of the present invention is to provide a simple andinexpensive cap or closure that is reusable as often as desired toeffect a seal to the mouth of the container and with each use theclosure can be applied so that it may not be removed without breaking aseal that is employed therewith.

A further object of the invention is to provide a reusable tamper proofseal closure that is easily and cheaply constructed and capable of longand hard use without becoming broken or out of order.

Other objects and advantages will be more apparent from the followingdescription wherein reference is had to the accompanying two sheets ofdrawings upon which:

Flg. l is a cross sectional view of the closure and a portion of theupper end of the container upon which the same is seated.

Fig. 2 is an enlarged fragmentary view of one side of the same.'

Fig. 3 is a fragmentary plan view showing the manner in which the tamperproof seal is applied to the closure.

Fig. 4 is a planv view of a modified form of construction wherein theparts which prevent the removal of the container are multiplied to showthe manner in which more than twocan be Vutilized; and

Fig. 5 is a fragmentary plan view showing the parts of the tamper proofseal in changed position so that the closure can be removed.

In the embodiment of the invention which I,

have chosen to describe and which is illustrated in the accompanyingdrawings:

In Fig. 1 I have shown a closure member consisting of two principalsheet metal members Il and I2 forming a top or cap member and anouter'member or retainer ring respectively. The cap Il, which is formedoi sheet metal bent'to the desired size and shape, may be in the natureof a cover portion for a comparatively large open mouthed container I4which is preferably formed with the rolled over mouth portion I4. Thecontainer is also provided with a circular ridge II about the neck ofthe same. disposed a short distance below the opening in the container.

The cap member I0 may be of a size to overlie the 'opening in thecontainer and have a concave top portion terminating in a ilat portion2l in which a circular rectangularly shaped groove 22 is providedslightly larger in size than the mouth portion I6 of the container. Iprovide a rubber or other similar resilient gasket 24 which is mountedin the groove 22 and adapted when the cap is in a sealing position torest against the top ofthe opening I6. The cap member I0 has a portion26 extending beyond the edge of the opening I6 which is formed withdownwardly projecting nger members 23. The nger members are formed withthe transverse bends 32 and the inwardly rolled lower edges 34.

' The outer or retainer member I2 may be formed with a circular ridge 36terminating at its inner edge in a ilat portion 38 resting on theportion 2i of the cap I0 and an arcuately disposed opening 39 formedthereby which permits the positioning of the same over the groove 22formed in the cap member I'Il. The member I2 may also have adownwardly'depending skirt 40 having an external bead or flange 42 atits lower end. The bead or flange imparts strength to the member .andalso provides a convenient nger grip for manipulating the retainermember in applying or vremoving the cap.

The cap or closure member as thus far described may embody generally theelements of the patent to theapplicant heretofore mentioned. In additionthereto, and to provide a tamper proof seal for a reusable cap of thetypel described, I provide a plurality of lug members 50 which may bepositioned upon pivot members 52 welded or otherwise secured onflattened portions 54 of the top 2li of the cap. The pivot -member 52may have a shank as shown and have its upper portion curled over asshown at 56 to position the lug 50. Each of the lugs 50 may have a legportion 53 adapted to overlie the at portion 33 of the retainer memberI2. Each lug is also provided with an upwardly turned leg 30 which has ahole 62 therein. Thus as shown in Fig. 3, a sealing wire 64 may be 3extended through the openings 62 drawn taut and have its ends sealedtogether with a lead seal S. In this position the lugs 50 cannot beturned with the result that the retainer member cannot be raised topermit the cap to be taken from the container.

In Fig. 4, I have shown a modified form oi' construction wherein Iprovide three lug members 50 positioned upon three platforms 54 on thetop of the cap I0. Thus, where the diameter of the container and coverbecome larger, the number of sealing lugs 50 is increased so that whenthe cover is sealed upon the container a sealing wire 64 may be drawnthrough the openings 62 in the lugs pulled taut and the two endsconnected together with a lead seal S.

In Fig. 5, I have shown the position to which the lugs 50 are turnedwhen the seal is broken, the sealing wire removed and the container isready to be opened. It will be noted that in this position the leg 58 ofthe lug 50 has been moved away from its position overlying the lip 38 ofthe outer retainer member I2.

While I have illustrated and described a specific embodiment of theinvention, it will be apparent to those skilled in the art that changesand modifications can be made in the exact details shown and I do notwish to be limited in any particular: rather what I desire to secure andprotect by Letters Patent of the United States is:
